TWO-HEAD ROTTABLE FA-STENING DEVICE.

Application filed May 28,

To al( whom t may concern.' y,

Be it known that I, ACHILLE FnA'NQois AYMoND, a citizen of France, anda resident of Grenoble, Isere Department, France, havek invented certain new and useful Improvements in Two-Head Rotatable Fastening Devices; and'I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same, reference being had to the accompanying drawings, und to letters or figures of reference marked thereon, which form a part lof this specification.

The closing by means of presslnittons yor studs, or of rotatable fasteners, that is to say by means of Jfasteners comprising a shank the revolution of which permits the ielease or engagement of an eyelet upon thebody of the fastener etc., as used heretofore to close the curtains of motor car hoods of tents, and the like, have the disadvantage that they allow the fastening or unfastening only from the side where the head of the dcvice stands, that is to say either from inside or from outside.

ln order to avoid this disadvantage, ap' plicant has devised the fastener forming the subject-matter of` the present invention which particularly characterized bythe that the shank of the rotatable fastening device passes entirely through the body 'of the button or fastener and also through the part to which the same is secured and is: provided, at the end opposite the one carrying the usual head, with a'second head allowing the same to operate either from outside or from inside.

The present invention has for a further obiect a way of securing this two head fastener to :1 fabric or leather such as a. hood er curtain as used in motor cars, this scour-- ing being obtained by means ofy rings provided with prongs engaging both sides of the. fabric and enclosing the socket part vof the fastener, the said rings acting as closing heads being connected together through clinchiug of the prongs. This inventionalso relates to the construction and mounting of the second head of the rotatable fastener,

Another object of the present invention consists in an impjro-igement to the fastening of curtains by means of this two head yfastener., which essentially resides in thepro.-

vision, on the internal face of the curtain, of tongues, or` of a suitable fold, preferably maintained through thezeyelets of the fasteners or studs, so as tovfacilitate the opening and specially the closing operation of the fasteners for somebody sitting inside the motor car, by allowing lto pull the tongues yor the fold vand consequently the curtain. l

Another object of the invention consists in an arrangement of this two head fastener vshank of which passes through the body of the rotatable part- (which comprises internally a coil spring or leaf) and is so mounted as to be able torevolve without being capable however of coming out of the latter, and of a second head passing through a socket Vof oval shape or any other shape whichisadapted to be secured to the other side of the wall `and in which the second head can revolve without coming out, the connection of the Shanks which is an extension of vthe fastener heads being effected in any suitable manner, such as sleeving on, threading, pinning and the like.

The following specification will allow an understanding ofthe invention with refer ence to the accompanying drawing given by way of example, in which:

`Figs. 3l to 33 are respectively schematic sections of modified forins of .construction of the rotatable fastener'.

In the arrangement shewn in Figures l and i2, the fastening deviceis composed Yin the usual V`manner of a stud or socket a, of o Ial section or `any other shape, secured by any suitable means, to one of the fabric or canvas parts, b for example. Inside 4this socket or cup a isarranged a square shank c connected with'the ordinary head e.

A. coil spring Z bears upon'acollar of the shank c and applies the head e connected with the lat-terinto grooves yprovided in a well knownfrnanner upon the cover of the socket a, in order to ste'a'dy'the said head at the required place corresponding to the opening and closing position of the fastener and to allow the eyelet g1 to stop the head of the key or to let the saine pass.

According to the invention, to the free end of the shank c is riveted or secured by any o ther ineans a second head f, constituted for example by a circular metal sheet which is suitably folded or bent over. The second side g of the fabric or canvas to be fastened is connected with the eyelet g1 which covers the socket a, as shewn in Fig. 1.

The releasing and closing of the fastener are effected in the usual manner by ineans of the head c frein the side where the body of the rotatable fastener stands; on the other side the fastening and unfastening are obtained in cansino' the second head to rotate inthe required direction.

In vthe modified forni of construction shewn in Figures 3 and 5ms, the shank c is maintained in the well known inanner in the vsuitable positions at one with reference to tlieother corresponding to the fastening and unfastening positions of the device by two leaf springs itl, if located inside the socket a and bearing upon two opposed faces of the square shank c. The construction, as shewn in Figure 3, refers to a two-head fastener as used for securing a strip of fabric or leather g to a wooden or instal wall or partition c'. The shank 0 is of sufficient length to extend through the thickness of the wall 2'.

Figures if, 5 and 6 show a leaf-spring rotatable fastening device as used for connecting together two fieziible parts g, Z), which are the sides of the canvas of a tent, hood, and the like. r'ihe second head j of the fas- L tener is inade of a metal leaf curved for efenplc in the shape of a bow, as shewn in Fig re fi. rihe top of this bow is provided with a circular holeA f1 allowing the passage of the die for riveting the head f to the key c.

Figure '.7 shows an arrangement of the fastener in which the eyelet g1 is covered in the usual manner by a plate g2 giving to the saine aneater appearance.

Finally, Figures 8 and 9 show fastening device provided with two cups or sockets 61, a2 which are arranged opposite each other and are secured to the fabric 7) to be connected. `One of these sockets only, for ample, the socket (il, contains the spring leaves 701, 72.2, the other one being inade of wood, of nietal or any other inater. This arrangement allows of securing the eyelet g1 to one or the other side of the canvas Zi, as shewn in full lines and in dash and dotted lines in Figure 9. This device can also be secured to a rigid or stiff part in order to connect the saine with a flexible one.

In order to facilitate the fastening of the eyelet or of the body of the rotatable device to flexible parts made of fabric, leather and the' like, there is secured to the underpart nrfrogeeiv of the eyelet, or under the socket, a tongue Inade of leather, fabric or any; other suitable material which allowsof exerting. the pull which is necessary in order to bringthe eyelet upon the body of the fastener.

This tongue can moreover be constituted by a simple fold of the flexible shewn in F igures2, 5 and 9. i

The socket a Lthe basey of which is perforated at a0 (Figure 11) is placed upon the fabric o which is also provided with an opening for the passage 0f the head f and with slots corresponding to the holesa) of the base a and serving for the passage ofprongs f Z1v of the upper ring Z. v

This ring Z isin factgconstituted (Figs 12 and .13) by an oval ring Z having the form of the base of socket a and is provided on its inner edge with prongs or claws Z1, as shewn in Figures 12 and 13. The lower ring (Figures 14 and 15)V consists in a disc l'm provided at m1 with slots which are conveniently located and through which the prongs Z1 passand with ya central opening Vm2 traversedk by the head f. This disc is preferably ianged around its periphery so as to form bulged parts M.

In order to secure the fastener or stud to the fabric fb, the socket a being placed in position, thelatter is covered byv means of the upper ring Z the prongs Z1 of which pass through the holes a0 and the slots provided in the fabric Z). Then thering m is engaged by its lower-,part (Fig. 10) so as to cause the prongs VZ1 to enter the slots m1. It is only necessary then to fold down the prongs Z1, as shewn in Fig. 10, in order to obtain a strong` securing of the socket a to the fabric b; in this operation, theends of the prongs Z1 enter, as shewn in Figure 10, between the bulged parts m covering the same.

The second head fof the rotatable fastener can be constituted by a flanged part fo, Figure 16, having the forni of an hollow half-disc. -After the internal spring (Z `of the rotatable fastener has been mounted and the sleeve of the supporting disc 0 has beenV set in position (Figure 10), the latter being engaged upon theshank c and pressing the spring rZ against the bot-toni of the socket a, the end of the shank c is opened, and then covered with the flanged part fo which is afterwardsv clamped upon the said end, as shewn in Fig. 17.

Zhen the curtains' 1, 2 of a. tent or of a motor car, are connected together by ineans of the rotatable fastener and the second head f of this fastener is directed towards the interior of the car or of the tent, but little difficulty is encountered when it is desired toA rpart g, as.

is desired to make use of one of the niost interesting conveniences which is secured by the utilization of the above described twohead rotatable fastening, a certain diiiiculty is encountered in bringing the curtain 1 carrying the socket part or eyelet, against the curtain, whereas this curtain 1 affords no seizing or grasping for the operation.

kIn order to avoid this, the curtain 1 is inwardlyvfolded at'; this fold 3 extends beyond the edge 2a of the curtain 2 can thus be seized orgrasped, as shewn in Figure 20, by the left hand between the thuinb and the fore-finger (position of Figure 20) and pulled so as to `bring the socket part g1 upon the stud part (position .of Fig. 19). It is then only necessary to turn the headA f with theright hand in vorder to bring together and close the curtains. .Y i I The fold 3 can be yreplaced by a single tongue 4 preferably located as high as the rotatable fastener'and held in the eyelet`g1 of the fastener when' placedupon the curtain, 'as shewniin Figure 21. This ligure shows the fastening toan upright 5 of the car-body oftwofcurtains 1 and 2 each one of which carries eyelets or socket parts g1 which engage the head@ of a two-head rotatable fastener arranged in the upright 5 of the car. body. Y

. To close the curtains from within the car, it is only necessaryv to null successively the tongues 41 and 4 projecting froni the upright 5 so as to engage theeyelets g1 on the body of the fastener, then in holding the tongue 4 with the left hand for instance to cause the head to pivot with the right hand (Figure 22) so as to close the fastener.

Figure 23 shows the arrangement of one tongue 4, to the curtain 1 secured by ineansv tends on a certain length beyond this body c1, while preserving its square section. A spring (Z is provided, in the usual manner, within the body c1 of the fastener so vas to press the head @against the body c1. The shank 711 is yieldingly maintained in the body c1 through a sort of collar e1 connected with the shank b1 and vbearing against the bottoni plate e1 of the rotatable fastener, the said plate acting Las a bearing for the spring d; this plate e1 is somewhat loose within the body of the fastener so 'as Ito lbe able of slightly sliding iu followingthe movement of the key head which moves up and down in its rotary motion "when passing` the notches of the fastener body and strains or relaxes the -coil spring which is confined between the bottom 'of 'they fixed bot y el of the fastener andthe plate c1.

2. A second fastener `head (Figure 28) which has in the drawing the form of=a `key /t' but ywhich could be replaced by a 'more'or less flattened oval stud or button or by a loop. f-'t square shank g2, connected with the head j' traverses a socket '7L of oval or other shape which is used for 'fixing the head to the wall, a collar or washer l is lconnected with the shank g2, that is to say is soldered, pinned or riveted to the shank. This collar l could moreover be replaced by lugs cut from the shank. This arrangement allows the shank g2 lto rotate in the socket h while preventing the same from-coming out therefrom. The socket 7a, as'shewn in Fig. 25 is of oval shape. This shape is preferably adopted because it enables one to find out the positionof the key 4Correspending to the opening' or closing' of the fastener, more conveniently than any other shape, but of course any other form could be eventually preferred.

3. A. tube (Figure 27) having an inter-nal section capable of insuring a driving action such as a square, rectangular oval or polygonal section and which is preferably longer than the longest of the shanks 61., g2 and which can be applied upon the latter so as to connect them together.

The securing ofthe rotatable fastener is effected in the same manner in case -the same is used in connection with a motor car.

ln the wall 7c (Fig. 29) of the car body is drilled a hole, of cylindrical form for example, whose diameter (Fig. 30) -is-greater than the diameter of the tube j so that the latter can freely turn in this hole. The body 01 of the first head of the rotatable fastener is secured to the face of the wall 7c which is adapted to receive the hood by means of screws Z2, or nails, claws, or any other means. The shank g2 of the second key is then introduced into the tube and the whole is engaged into the hole drilled in tbc car body. so that the shank 1 will enter the tube j; the two keys are then connected together and the socket is secured by any suitable means to the second face of the car body fr.

introducing the tube j upon the shank b1, care must be taken so that the 4'head be iu the same plane as the head o1 so that the positions of the two heads will be the same when opening or 'when closing and so that the movement of the keys, either from out side or from inside, cannot be confused.

The Afree lengths of the ends of shal'nks 1 and g2 ares-uch that when a certain 1portion of length ofthe tube j -is'added there-to, they will correspond to 'the normal thickness of the-car body, but 'it 'is obvious that they can be of Vany required sizes and that particularly in vthe case of 'thick car-bodies, vthe Shanks are made of a -greater Vlength `and df a greater thickness so as to'o'ie'r a sufficient resistance to the torsion o-f-fmetal.

The securing of the fastener to a wootlen wall has just been described, `but it "must be understood that `it could be secured to any kind of material, such as'nireta'l, plastic matters, and the like.

If it is desired to prevent the key ,f which generally points towards the interior 4ofthe car body 'from projecting from the 1lat-ter, the socket 'llt can bematle of an Ihollow form h3, as shewn 'in Figure 32, and this socket can be fixed in a recess 71,4 provided -in said car body, so as to constitute ya seat for the head which, as `she-wn in Figure 32, 'projects but slightly.

The head if can also be entirely concealed within 'the recess h5, as shewn in Figures 3l and33.

The way of connecti-ngtogther theshanks of the two keys of the rotatable fastener is capable of numerous alterations. F or example, as shewn in Figure '31, "these cylindrical 'shanks could `be Athreaded 'and screwed tightly within a tube jl which is tapped. In the Asame way the shank 1 can be hollow (Figure 33) and can receive at its end theshank 'g2 which eliminates the tube j.

Finally, this 'tube j could still 'be provided at its two ends with portions j?, je' of va square section, which Vwould enter into the Shanks b1 and g2 of tubular form with a square 'section (Fig. 32).

At last, the tube j could be flush with the interior of the car body on the side, where the second head lies, the saine bei-ng then secured to thetube jby means of pins, or the like. y

lDe-tail alterations may ybe made `to the present invention without departing from its principle.
